On March 4, the Tennessee Aquarium IMAX 3D Theater will premiere Ocean Odyssey 3D, a new giant-screen adventure focusing on the vital role the “blue heart of the planet” plays in shaping life above and below the waves. To celebrate the film’s arrival at our theater, we met with the film’s writer/director, Nick Robinson, to discuss animals’ use of oceanic currents as underwater superhighways, how Finding Nemo inspired him and collaborating with celebrated oceanographer and advocate Dr. Sylvia Earle.
